Mud-dauber Wasp demonstrates superiority

I've had a weekend off, but in my absence a tiny little Mud-dauber Wasp appropriated a small corner of the little red window to create an entire purpose-built adobe home for its family, installed the future family in it and stocked the larder with * horror alert * tiny little live paralysed spiders.  Isn't nature grand?

The workwomanship is simply exquisite.  You can just see in the photo the different mud colours.  The wasp has identified that the lighter colour mud from Hepburn is better for building, then it has used our own terra-cotta coloured earth to make it pretty, or camouflage it, or whatever.  It's altogether slightly Attenborough, yes?
